The Curtis high frequency battery chargers are portable and allow easy charging of industrial vehicle batteries from 24 VDC to 48 VDC using any standard outlet in the world. provides 900 to 960 Watts at output voltages of 24, 36 and 48 VDC. battery chargers are ideal for use in material handling, airport, golf, aerial lift, sweeper/scrubber, utility, Light- On-Road and general industrial battery-powered vehicles. FEATURES Rugged, sealed aluminum die cast enclosure protects against extreme environments. Integrated USB port allows easy updating of software, charge profiles and retrieval of charge history. Wide range AC mains input (85 270 VAC) allows use of one charger anywhere in the world and eliminates the need to stock and service multiple models. Convection cooling eliminates the need for a cooling fan, thereby increasing reliability and eliminating the need for fan replacement/service. Advanced, high-frequency, switchmode design allows more efficient (90% typ), faster charging and optimal charging independent of battery type or condition. IP66 protection allows reliable operation in harsh environments. Power Factor of >0.98 minimizes utility surcharges and optimizes the use of AC line power. Select from an extensive list of approved charge algorithms (default I 1, I 2, U, I 3 ). The chargers can store 25 separate algorithms which can be selected to match the specific batteries in use, thereby eliminating the need for multiple models and resulting in lower operating costs. Lightweight and compact size allows on-board use and offers space advantages over ferro-resonant chargers in traditional off-board installations. www.curtisinstruments.com 2
